The table was rather high, at about 3 feet. On the floor was a plastic chair mat, on a hard wood floor. The disk was 1 TB Western Digital Caviar Black (WD1002FAEX) manufactured in March of 2010 that I was replacing. It was unplugged, in case that's not obvious.
Since I already retired the disk, I was only keeping it around as a backup (it's part of a RAID set, actually). So, no tragedy if it was lost. Still, my curiosity got the better of me and I plugged it back in. The drive exposed 3 types of self-tests, via SMART: short, conveyance, and long. All three passed, and I saw no indication of any errors in either the error log or any of the other SMART statistics that I could query. I'm sure the long test actually did a surface scan, since that's about how long it took. That's as far as I went, since any further checks would've required bringing the entire RAID back online.
Wow. I'm sure there are potential impact points, such as the connector block, which would've killed it. But I'm still impressed that it survived such a mechanical shock. I've seen many hard disk spec sheets that quote like 300 G non-operating shock, but it's still impressive when you actually see it in person, with a device having probably sub-micron operational tolerances.
I should add that however it landed, there's a mark on label from where it also hit the metal base of my chair.
